I'd like to know. What is the most balls out, loudest cat-back exhaust system you can buy for a third-gen camaro. I know you can buy those slp loudmouth exhaust kits for fourth-gens but do they make a kit for third-gens? If not, what would compare with them?

I'm partial to the GMMG catback. Its pretty loud, definitely noticeable, but sounds great. The Loudmouth is too obnoxious to me.

i'm not sure about the loudest, but i have 2.5" off the headers, they y pipe into 3" and into a flomaster 40 series muffler. my car is too loud and i'm thinking about getting something with less rumble.

Its all a matter of preference. I have a magnaflow catback that was tweaked from a 4th gen on my iroc. its loud under throttle and load but at an idle is quiet which is what i wanted. some of my friends said they can hear me a few blocks away with it.

I was looking at the GMMG, they are beautiful pieces, loud and just awesome. unfortunately my budget at the time restricted me on what i could get otherwise it would have been a gmmg.

No muffler would be the loudest cat back...the cats do most of the muffling and choke most of the performance. I swapped in an X pipe in place of my cats on my 97 C5 and it picked up 12 rear tq and about 5 hp. A catback (flowmaster etc...) does nothing but improve the sound.

You'll need headers to achieve "loud".

I also have the 4th gen Magnaflow system on my car. It's loud at WOT.

Your engine will also determine how loud your car will be. Cam, heads and displacement all play a role in the level of noise.

a lot of the time really loud exhausts on a third gen f-body end up sound like a pissed off dump truck. This is due to a pos worked over 350 from a truck.

But if you must have stupid loud cat-back id recommend a Edelbrock SDT 3" catback. I have a vid of my car but its got a cat and worn out 305 right now.

BUT what i plan on doing for my BUILT 1992 trans am is a longtube header to 2.5" pipes then to dynomax race bullets and dumping before rear axle. Very loud but sounds great when you ahve horsepower

I'm running SLP headers dumped right after the y-pipe behind the passengers side front tire. Its a mildly cam (204/214* duration at .050") 305, but it sounds pretty decent, very slight chop at idle, pretty noisy at cruise, and absolutely brutal at WOT shifting at 5500rpm.

Everybodies definition of loud will vary. You can get an idea what certain systems sound like on videos, but there is a lot of variation even in that. The point is, find some cars you can actually go and physically see, and then decide what you like.

Power makes noise.........Noise does NOT make power

^ what he said

you can put a straight pipe on a stock motor and make it loud, but it will sound awful! You cant beat the sound of a good healthy motor and a big cam.

Mufflex systems with the spintech muffler sound great too, but are pricey and flow like sheet.

As for the guy who said cats choke performance, thats not true. A good high flow cat will only cost you a few horses and keep the car from smelling bad.

Im running a 4" catback with dual 3" cats and a dynatech race muffler, its loud, but a good sounding loud. And smells nice.

What ever you do, don't make your car a ****** mobile. Don't attempt to run dual exhaust, don't just take your muffler off etc.

Start with buying a catback system, and then get headers and a y pipe when you can afford them. It'll LOOK good, sound good, be easy to install and will not cause you headaches down the road.

I recommend the Hooker catback for our cars. I think it is reasonably priced, sounds different, and will sound good (aka be "loud")

I agree with that. I had just a cat and it was pretty loud. It wasn't race car loud but still ridiculous. If you want just loud go with that. Nothing is as loud as what I have now though, headers into nothing.

For nice/loud I like Flowmaster and the SLP LM2. For just plain loud, chambered mufflers and LM1 type of exhausts work, I'm not one for their sound much though. They just kinda sound like cars that had their mufflers fall off, esp the LM1. I'd take sound quality over noise.

I like the mufflex 3 1/2 with spintech... It's plenty loud.

Here's mine: http://www.youtube.com/watch?v=kfLWpAy0c1o

:drool:

Cool car! What does it run?

Save up for a little while and go for the GMMG. GO to their website GMMGINC.Net and listen to the videos and you will see. $750 or so for the system+tips...

No official 1/4 mile track time yet, I only have time to drive the car a couple of times per year if I'm lucky.

I ran it in the 1/8th once, but was having major problems that day (TPS broken, running so rich it fouled the plugs, and figured out that a Mcleod single disk "LT-4 replacement" clutch wasn't worth a crap when the car hooks!)....

From the cars with time slips that I've seen that I've raced and beaten (red light to 115 or so), I figure the car has at best an 11.9 to probably a consistent low 12 in it. Not super fast, but still a pretty fun ride!

GO LOUD
BE PROUD
Make The Neighbors Pout

My setup coming soon (Going for name, not sound; name to be different (flowmaster is to common round my parts, and not sound because, well I plan on changing this car many times over, sound will change as well)

Hooker 2055 Sterling Coated
Magnaflow 3" Cat Polished
Magnaflow Camaro/Firebird Muffler
Magnaflow Non-Rolled, 45* Slash Cut, 18" Long Exhaust Tips

Enjoy and let us know when you get it done, I want to hear the setup.

With my 280h cam, this is plenty loud

I don't necessarily agree with this. Most of the really loud cars I see, including mine, get schooled on the dyno and on the strip by far less obnoxiously loud cars. Smart makes power, clueless makes noise. Unfortunately, I'm still in the second group.

TA

I went with Hooker 2210's with a Mufflex y to a 4" exhaust all the way out to a spintech dual out muffler. It is loud but it really needed to breath. I used the method Air in = Air out. A single 4" can outflow two 3" duals. Takes a little bit more consideration when running the pipes though.

if you want power loud isnt the way to go. I just went from a flowmaster to a borla pro xs and it is almost as quiet as stock when idling but down on it has a nice tone but still way quieter than the flowmaster and in the muffler shootout the borla was top of the heap. The straight though design mufflers like borla and dynomax ultra flow are the best for power and even though you look right through it they are nice and quiet. now the bullet is terribly loud but make good power not as much as the others though.
